Our line of back check valves comprise of full port swing style and traditional disk style. Our swing style are “full Port”, which means the hole size inside the valve is the same size as the pipe thread. Nearly no restriction in the through hole and with the swing valve style seat assembly that swings out of the flow when in use you can rest assured you won’t be restricting flow when you need it. The internal mechanisms are stainless steel to prevent rust and corrosion due to N-serve or other additives. Our traditional syle back check is a disk style check and is generally used for storage tank applications.
